title: [Glycosaminoglycans in the brain of rats subjected to electromagnetic field action].
abstract: Investigations on changes of glucosaminoglycans content were carried out in the brain of the rats irradiated once (30 min.) or several times (2-6 hours daily). The following frequencies of e-m fields were used: 2880 MHz (pulse modulation 1000 Hz, pulse duration 1,5 mus); 150 MHz (50 V/m); 175 MHz (150 V/m); 3000 MHz c.w. continuous wave). Control groups of animals were not subject to irradiation. Statistically significant increase of GAG content was found in the brain of the rats, irradiated in e-m field of frequency 2880 MHz in comparison with GAG concentration in the controls. In the brains of animals exposed to e-m fields of frequencies 150 and 175 MHz a statistically significant decrease of GAG content was noted in comparison with GAG content in the controls. Whereas e-m field of frequency 3000 MHz c.w. did not induce statistically significant changes in GAG content in experimental animals as compared with the controls.
